Scope

This document is applicable to the integrity assessment of fixed pressure vessels (hydrogen storage vessels and liquid hydrogen storage pressure vessels), hydrogen-related pipelines, rotating equipment (hydrogen compressors, liquid hydrogen booster pumps, etc.), hydrogen filling machines, and interface/support subsystems directly related to integrity (limited to instruments/electrical/interlocking devices coupled with pressure-resistant safety functions) in hydrogen/liquid hydrogen filling stations. Other pressure equipment within the station can be implemented in accordance with this document.
